Description

Technical Field

[0001] This utility model relates to the technical field of tension testing equipment, specifically to an instrument for testing the tension of flexible components. Background Technology

[0002] Before flexible components such as timing belts and timing ropes can operate, their tension usually needs to be adjusted to meet the transmission requirements. If the tension is insufficient, transmission will be difficult, while if the tension is too high, the flexible components will be prone to excessive wear and damage during transmission.

[0003] Currently, the tension of flexible components is usually tested manually after on-site installation. However, manual testing is based on human subjective judgment, so the test results are not accurate enough and it is time-consuming and labor-intensive.

[0004] Based on this, the present invention aims to provide a solution to the above-mentioned problems. Utility Model Content

[0014] In one specific embodiment, the first clamping plate and the second clamping plate on the same side extend opposite each other at least one edge to form an anti-detachment plate for abutting against the flexible member.

[0015] In one specific embodiment, the scale includes an arc scale disposed on one of the first clamping arm and the second clamping arm, the center of the arc scale being located at the hinge point of the first clamping arm and the second clamping arm.

[0016] In one specific embodiment, a notch is provided on one of the first clamping arms and the other of the second clamping arms near the scale, and the edge of the notch corresponds to a graduation on the scale.

[0029] In various embodiments of this utility model, the expression "or" or "at least one of A and / or B" includes any combination or all combinations of the words listed simultaneously. For example, the expression "A or B" or "at least one of A and / or B" may include A, may include B, or may include both A and B.

[0030] The terms used in the various embodiments of this utility model (such as "first," "second," etc.) may modify various constituent elements in the various embodiments, but do not limit the corresponding constituent elements. For example, the above terms do not limit the order and / or importance of the elements. The above terms are only used for the purpose of distinguishing one element from other elements.

For example, without departing from the scope of the various embodiments of this utility model, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.

[0031] It should be noted that, in this utility model, unless otherwise explicitly specified and defined, terms such as "installation," "connection," and "fixation" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Please refer to Figures 1 to 4 The present invention provides a flexible component tension testing instrument, comprising: a first clamping arm 1, a second clamping arm 2, an elastic component 3, a scale 4 for measuring the intersecting angle between the first clamping arm 1 and the second clamping arm 2, a first clamping part 5 for clamping an external flexible component, and a second clamping part 6 clamping the elastic component 3.

[0033] Specifically, the middle regions of the first clamping arm 1 and the second clamping arm 2 are hinged. The middle region of the two is the non-end region of the first clamping arm 1 and the second clamping arm 2. The middle region is not limited to the center of the first clamping arm 1 and the second clamping arm 2.

[0034] One side of the first clamping arm 1 and the second clamping arm 2 are connected to the first clamping part 5, and the other side of the first clamping arm 1 and the second clamping arm 2 are connected to the second clamping part 6. The second clamping part 6 is driven by the elastic member 3, which in turn causes the cross angle of the first clamping arm 1 and the second clamping arm 2 to change, thereby causing the clamped flexible member to deform.

[0035] Optionally, the first clamping part 5 and the second clamping part 6 can be integrally formed with the first clamping arm 1 and the second clamping arm 2, or they can be connected separately.

[0036] Please refer to Figure 1Understandably, the second clamping part 6 clamps the elastic member 3. Due to being clamped, the elastic member 3 generates a certain elastic restoring force. This elastic restoring force acts on the first clamping arm 1 and the second clamping arm 2, thereby causing the angle between the first clamping arm 1 and the second clamping arm 2 to change, so that the other ends of the first clamping arm 1 and the second clamping arm 2 tend to move closer to each other. Thus, the first clamping part 5 is provided with a clamping force to clamp the external flexible member, and the flexible member deforms under the action of the clamping force.

[0037] For example, please refer to again Figure 1 Taking the flexible element as the synchronous belt 7 as an example, the synchronous belt 7 is wound around two rollers 8 and tensioned. In use, the first clamping part 5 clamps the upper and lower parts of the synchronous belt 7, causing the upper and lower parts of the synchronous belt 7 to deform towards each other. Since the flexible element is in a tensioned state, a certain restoring force is generated after deformation. This restoring force counteracts the clamping force applied by the first clamping part 5, and eventually balances with the clamping force. After balance, the staggered angle between the first clamping arm 1 and the second clamping arm 2 is obtained by observing the scale 4. It can be understood that the larger the staggered angle, the smaller the deformation of the synchronous belt 7 and the greater the tension of the synchronous belt 7; conversely, the smaller the staggered angle, the greater the deformation of the synchronous belt 7 and the less tension of the synchronous belt 7.

[0038] Optionally, the scale 4 can be set on one of the first clamping arm 1 and the second clamping arm 2, or it can be separated from the first clamping arm 1 and the second clamping arm 2.

[0039] This utility model has a compact structure and is easy to use. It can be used for testing and adjusting the tension of flexible components. During the tension adjustment process, the first clamping part 5 is always clamped onto the flexible component. The tension is adjusted, and the angle between the first clamping arm 1 and the second clamping arm 2 is observed using the scale 4. When the angle between the first clamping arm 1 and the second clamping arm 2 reaches the target value, it indicates that the tension of the flexible component is properly adjusted.

[0040] In one specific embodiment, please refer to Figure 1 and Figure 3 The first clamping arm 1 has a first clamping plate 9 on both sides, and the second clamping arm 2 has a second clamping plate 10 on both sides. The first clamping plate 9 and the second clamping plate 10 located on the same side are arranged vertically opposite each other, thereby forming the first clamping part 5 and the second clamping part 6.

[0041] Specifically, the first clamping plate 9 and the second clamping plate 10 of the second clamping part 6 abut against both ends of the elastic member 3, thereby clamping the elastic member 3. In actual use, the first clamping plate 9 of the first clamping part 5 may abut against the lower part of the flexible member, and the second clamping plate 10 of the first clamping part 5 may abut against the upper part of the flexible member, thereby clamping the flexible member in opposite directions.

[0042] It should be noted that the first clamping plate 9 and the second clamping plate 10 on both sides should have the same positional relationship. That is, if the first clamping plate 9 is on top and the second clamping plate 10 is on the bottom on one side, then the first clamping plate 9 is on top and the second clamping plate 10 is on the bottom on the other side as well.

[0043] Furthermore, at least one edge of the first clamping plate 9 and the second clamping plate 10 on the same side can extend towards each other, thereby forming an anti-detachment plate 11 for abutting the flexible member. Understandably, the anti-detachment plate 11 can abut the flexible member from the side, thereby restricting the flexible member from detaching from the clamping of the first clamping plate 9 and the second clamping plate 10, and improving the stability of the device.

[0044] For example, the anti-detachment plate 11 may be formed on one side edge of the first clamping plate 9 near the first clamping arm 1 and on one side edge of the second clamping plate 10 near the second clamping plate 2, such that the first clamping plate 9 and the second clamping plate 10 can be connected to the first clamping arm 1 and the second clamping arm 2 through the anti-detachment plate 11.

[0045] In one specific embodiment, please refer to Figure 1 and Figure 2 The second clamping part 6 may be provided with a fixing post 12, and the elastic element 3 may include a compression spring 31 wound around the fixing post 12. The second clamping part 6 abuts against both ends of the compression spring 31. It can be seen that by sleeved compression spring 31 on the fixing post 12, the stability of compression spring 31 when clamped can be improved, and the compression spring 31 can be prevented from disengaging from the device.

[0046] For example, in an embodiment where the second clamping part 6 includes a first clamping plate 9 and a second clamping plate 10, the fixing post 12 can be a screw 121. The screw 121 passes through the first clamping plate 9 and the second clamping plate 10. One end of the screw 121 abuts against the bottom of the first clamping plate 9, and the other end of the screw 121 is connected to a nut 13. The nut 13 is used to abut against the top of the second clamping plate 10, thereby restricting the movement of the first clamping plate 9 and the second clamping plate 10 along the direction of the screw 121.

[0047] Furthermore, in this embodiment, a cover 14 may also be included, and the two ends of the compression spring 31 can respectively abut against the second clamping part 6 through the cover 14. Specifically, the screw 121 mentioned above also passes through the cover 14, thereby preventing the cover 14 from disengaging from the device. The cover 14 may be in the form of... Figure 2The bowl-shaped cover 14 shown has its sidewalls surrounding the compression spring 31, thereby limiting excessive lateral movement of the compression spring 31 and improving the stability of the device.

[0048] Furthermore, in this embodiment, a buffer 15 may also be included, and the side of the cover 14 facing away from the compression spring 31 abuts against the second clamping part 6 through the buffer 15.

[0049] For example, in an embodiment where the second clamping part 6 includes a first clamping plate 9 and a second clamping plate 10, the side of the cover 14 facing away from the compression spring 31 abuts against the first clamping plate 9 or the second clamping plate 10 via the buffer member 15. It is understood that the buffer member 15 prevents direct hard contact between the cover 14 and the clamping plate, thereby reducing noise and improving the service life of the compression spring 31, preventing it from failing due to frequent hard impacts.

[0050] Optionally, the buffer 15 can be a washer made of rubber, plastic or other materials.

[0051] In one specific embodiment, please refer to Figure 1 and Figure 3 The scale 4 may include an arc scale 4 disposed on one of the first clamping arm 1 and the second clamping arm 2. For example, the arc scale 4 may be fixedly connected to the first clamping arm 1 by a rivet 16, the center of the arc scale 4 is located at the hinge of the first clamping arm 1 and the second clamping arm 2, and the scale on the arc scale 4 is also in the shape of an arc with the hinge as the center.

[0052] Understandably, during use, the first clamping arm 1 and the second clamping arm 2 will rotate relative to each other with the hinge as the fulcrum. Therefore, by setting an arc scale 4 with the hinge as the center, the intersecting angle between the first clamping arm 1 and the second clamping arm 2 can be better measured, thereby improving the accuracy of the final test results.

[0053] Furthermore, a notch 17 may be provided on one of the first clamping arm 1 and the second clamping arm 2 near the scale 4. For example, the notch 17 is provided on the second clamping arm 2 near the scale 4, and the edge of the notch 17 corresponds to a graduation on the scale 4 for reading the graduation value. Preferably, the extension line of this edge passes through the hinge point of the first clamping arm 1 and the second clamping arm 2, so that when the first clamping arm 1 and the second clamping arm 2 rotate relative to each other, the edge can always be aligned with the graduation on the arc scale 4, facilitating observation by the inspector.

[0054] In one specific embodiment, please refer to Figure 1 , 34. The first clamping arm 1 and the second clamping arm 2 can be hinged together by a bearing 19. Specifically, the inner ring of the bearing 19 is connected to a rotating shaft 20. One of the first clamping arm 1 and the second clamping arm 2 is fixedly connected to the rotating shaft 19, and the other of the first clamping arm 1 and the second clamping arm 2 is fixedly connected to the outer ring of the bearing 19. For example, the first clamping arm 1 is fixedly connected to the rotating shaft 20, thereby allowing the first clamping arm 1 to rotate relative to the outer ring of the bearing 19. The second clamping arm 2 is fixedly connected to the outer ring of the bearing 19, thus enabling the first clamping arm 1 and the second clamping arm 2 to rotate relative to each other, achieving the hinge connection between the first clamping arm 1 and the second clamping arm 2.

[0055] In summary, this utility model provides a flexible component tension testing instrument that can clamp an external flexible component using the first clamping part 5 and observe the cross angle between the first clamping arm 1 and the second clamping arm 2 when the flexible component is clamped using the scale 4, thereby obtaining the degree of deformation of the flexible component and determining its tension based on the degree of deformation. This utility model has a compact structure and is easy to use, making it suitable for flexible component tension testing and adjustment, providing a good user experience.
